I am able to upgrade it to 19.4 and compile successful. Attach for your reference.
Anyway, I aware about there are some P-tile PCIe issue that it is unable to run the data transfer test successfully. This issue is fixed in 201. So I'll recommend you to try on 20.1 if you wish to upgrade your design. QII Pro 20.1 already released.
Oh sorry, just aware about AN881 is not a P-Tile device. Please ignore my comment about p-tile PCIe issue. And user still suggest to use latest quartus version which is 20.1.
However, the design still able to compile in 19.4 at my side.
